Cylinder Requalification

Transport Canada mandates that all cylinders containing dangerous goods must be requalified at specific times using specific methods. The times and methods for the two types of cylinders in our industry are as follows:

RECOVERY CYLINDER – Any cylinder with a two way valve is considered to be a recovery cylinder. According to Transport Canada recovered refrigerant is considered potentially corrosive and could damage the inside of a cylinder over time. Therefore the following method and frequency of requalification must be followed:

Method: Hydrostatic volumetric expansion.

Requalification Frequency: 5 years after manufacturer date, every 5 years thereafter.

VIRGIN CYLINDER – Any cylinder with a one way valve that can only be accessed by a manufacturer or packager of virgin, or reclaimed refrigerant. Because the content of virgin cylinders is clean and free of oil and moisture, there is no concern of internal damage of these cylinders. Therefore the following method and frequency of requalification must be followed.

Method: Visual inspection

Requalification Frequency: 10 years after manufacturer date, every 10 years thereafter
